Title: Method for plastic restoration of annular ligament and endoprosthesis for after- resection substitution of the radial head
Inventor: KRASTANOV STEFAN N
IPC: A61F2/38
Filed: 1989-08-14
Abstract: The method and the endoprosthesis are applied in orthopaedy and traumatology of fresh and especially of old injuries. They allow to plastically recover the annular ligament and the post-resectional replacement of the radial head, at the use of automatic implant and implantation of endoprosthesis, which are reliably and securely fixed. At the implementation of the method, is resected the radius' head. In front of and behind the cryst ulne are formed cross tunnels, which exit on the medial surfaced of the bone. The front tunnel holds the first edge of a free sinew's implant. The endoprosthesis is implanted. The second edge of the implant is wound round its neck and is passed further to the rear tunnel. The two edges are stitched under moderate pressure. The endoprosthesis has a head (1), corresponding in form and size to the radial head and is statically to a conical stem (2) with a jigsawish threading (7). In the realm of linkage are formed two fixating prismatic bodies (3). Above them are made consecutively located first (4) and second (5) ring-shaped channels. The first ring-shaped channel (4) is holding an X-ray positive wire ring (6) of titanium wire.

Title: Single-use syringe
Inventor: AVILA LES
IPC: A61M5/178
Filed: 1989-12-14
Abstract: Page 3 of 9 ABSTRACT Conventional syringes share a common properly in that they are capable of re-loading and repeated discharges. Repeated use may result in microbial contamination of individuals and the spread of blood transmitted diseases such as Viral Hepatitis and Aquired Immuno-Defidence Syndrome (A.I.D.S), or in contaminating and falsing experimental results in the laboratory.   The SINGLE-USE SYRINGE is designated to overcome the above deficiencies by insuring that each syringe is mechanicaly capable of a single discharge only, and, consequently, is rendered inoperable, non-functional and obselete on completion of a single discharge.   Mechanical efforts to re-activate the SINGLE-USE SYRINGE will IPSO-FACTO destroy the physical mecanism of the syringe, rendering it completely end definitely unusable.

Patent CA-2010884-A1 (CA)
Inventor: SHERIDAN JOHN P
IPC: C05B21/00
Filed: 1990-02-26
Abstract: This invention relates to re-vegetation o fmine teailings deposit areas. Generally mine tailings are highly acidic, having a pH of 2.0 or lower on a continuing basis. Fly ash from sanitary incinerators may have high amounts of phosphates of calcium, magnesium, or aluminum. If the fly ash is spread on the mine tailings deposit area, and water is introduced, complex chemical reactions arise which may result in the production of metal sulphides and phosphoric acid or super-phosphates of the metals. In any event, if metal sulphides are produced they are generally stable, and the phosphoric acid or metal superphosphates will release phosphates in a useable manner to any vegetation being grown in the area where the fly ash has been spread on the acidic mine tailings deposit area.

Title: Fibre optic waveguide elements
IPC: F21V8/00
Filed: 1990-07-19
Abstract: A fibre optic element is disclosed capable of a wide range of uses,  including illumination,  lighted fixed or variable signs, and decorative applications. The element is formed in one piece of transparent material and has one or more generally planar areas with integral extensions from one or opposite sides formed as a number of separable filaments such that the filaments can be bunched to form a flexible light conducting cable. Except for light escape zones via which light can escape from the planar area or areas, and the distal ends of the filaments, the element is covered by an internally  reflective  cladding  layer  such  as  to  enable propagation of light through the filaments from the light source and in the plane of the planar areas, which rather than being strictly planar can be curved into various shapes. The light escape  zones may be  formed by replacing the cladding layer in those zones by a transparent layer of higher refractive index than the material of the element, or by using a diffusive or phosphorescent layer to divert or reradiate light out of the plane of the element.

Filed: 1990-11-08
Abstract: JUNCTION FIELD EFF~CT TRANSISTOR AND METHOD OF FABRICATING   Abstract A junction field effect transistor,  specifically a static induction transistor.   Prior to metallization a thin layer of germanium is placed over the exposed silicon of the  source and gate regions.   The germanium is intermixed with the underlying  silicGn  to  form  a germanium-silicon composite.  A rapid thermal anneal is performed  to  recrystallize  the  germanium-silicon composite.   Alternatively,  a single crystal epitaxial layer may be deposited on the silicon.   Conventional metallization procedures are employed to produce ohmic source and gate contact members to the germanium-silicon composite or the epitaxial germanium of the source and qate reglons.  By virtue of the reduced bandyap provided by the presence of the germanium, the contact re~istance of the device is reduced.

IPC: F23D14/16
Filed: 1990-11-29
Abstract: A method and apparatus for modulating the surface area of a radiant infrared burner over which combustion occurs as a function of burner heat output rate.  This modulation serves to maintain the heat flux density on the surface of the burner at or near an optimum value over a range of heat output rates.  The modulation is effected by means of a piston disposed in the internal cavity of a burner which blocks the passage of combustible gas to areas of the burner downstream of the piston from the gas inlet to the burner.  The piston is displaced further downstream with increased gas flow rate resulting in combustion occurring over an increased area of the burner surface as burner heat output rate is increased.  In its simplest embodiment, the invention comprises a burner oriented vertically with the combustible gas entering the bottom of the burner and a free piston which floats on the incoming gas stream at a level within the burner which is proportional to the gas flow rate.

The member has a central axis, the central axis being oriented substantially perpendicular to the bearing surface of the test block.  The force sensor further includes strain gages secured to the member and having an electrical characteristic indicative of force applied to the member by the tire under test.  A motion sensor is located within the longitudinally extending opening in the member.  The motion sensor includes an elongated pin having a tip extending beyond the bearing surface of the test block so that the tip penetrates the tread of the tire under test as the tire rolls over the motion sensor.  The motion sensor further includes strain gages secured to the pin and having an electrical characteristic indicative of the motion of the pin which is, in turn, indicative of the motion of the tread of the tire penetrated by the pin.
